To start the McCulloch M3546 S Lawn Mower, ensure the fuel tank is filled and the oil level is adequate. Set the throttle lever to the start position, engage the choke if necessary, and pull the starter rope firmly.
Use unleaded gasoline with a minimum octane rating of 87. Avoid using gasoline with more than 10% ethanol to prevent engine damage.
Change the oil after the first 5 hours of use, and then every 25 hours of operation or at the beginning of each mowing season.
Check the fuel level and ensure it's fresh. Verify the spark plug is clean and properly connected. Make sure the air filter is clean, and inspect the fuel line for blockages.
Remove the air filter cover, take out the filter, and clean it with soap and water if it's a foam filter. If it's a paper filter, gently tap it to remove debris or replace it if necessary.
Inspect the blades regularly for damage and sharpen them every 20-25 hours of use. Replace blades that are worn out or damaged beyond repair.
To adjust the cutting height, locate the height adjustment lever on each wheel and shift it to the desired position. Ensure all wheels are set to the same height.
Check for loose or damaged blades and ensure they are properly balanced. Inspect the engine mounting bolts and tighten them if necessary.
Inspect the spark plug every 25 hours of use or annually. Clean or replace it if it shows signs of wear or carbon buildup.
Clean the mower thoroughly, drain the fuel tank, and change the oil. Store it in a dry, sheltered location, and cover it to protect from dust and moisture.
